It is essential to upgrade the brakes when fitting a Rover V8 to a stock TR7. Even the uprated brakes fitted to genuine TR8's leave something to be desired.
Fortunately, there are a variety of brake upgrade options available:
- Stock TR8 (SD1): The top left photo shows this option. Genuine TR8 calipers are rare, but Rover SD1 calipers can be had. Original TR8 discs/rotors are readily available. We did have to add washers under the caliper housing bolts and trim a small amount of material off the backing plates. The outer pad was a very tight fit initially but otherwise the SD1 calipers appear to work fine, and unlike the TR8 calipers the steel wheels do not seem to foul on the calipers.
- Volvo derived: This four piston, vented rotor kit offers greater braking capacity but at over $1000 is somewhat pricey. However, the vendor claims that the 13" steel wheels can be reused thus the cost is considerably offset by not having to purchase new wheels and tyres.
- Rover Vitesse derived: This kit also offers four piston, vented discs but requires a minimum of 14" diameter wheels/tyres.
- Other Options: Details to follow...................
